UNDERJBODY FOR TANK-CARS.

Specification of Letters Patent.

Patented Dec. 1, 1914i.

To allrwhom ltfmay concern:

Be it known that I, JOHN FRANKLIN connection with the accompanying sheet of drawings, forms a full, clear, andv exact M of specification, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates generally to improvements in an underbody for tank cars, and it consists, essentially, in the novel and peculiar combination of parts and details of construction, as hereinafter first fully set forth and described and then pointed out in the claims.

This invention has for its object the provision of a structure which will possess a certain resiliency so as to partially dissipate the strains and stresses peculiar to tank cars.

. In the drawings already referred to which serve to illustrate my said invention more fully, Figure 1 is a fragmentary side elevation of one end of a tank car illustrating the coperation ofthe tank with the underframin Fig. 2 is a vertical section taken along l1ne 2-2 of Fig. 1. Fig. 3 is a similar view taken along line 3-3 of Fig. 1 to illustrate the bolster construction.

Like parts are designated by corresponding characters or symbols in all the figures of the drawings.

Reference being had more particularly to the drawings, A indicates generally a girder extending throughout the entire length of the car and which constitutes the main support for the tank 10. This girder A is composed of the vertical channel bars 11 secured together along their upper flanges at intervals by the to plates 12 bolted or riveted to the said anges; and along their lower flanges by the bottom plate 13 which is located medially of the length of the girder Located a suitable distance from car bolster B, described and claimed in a (Jo-pending application llo. 831,464 and riv eted transversely of i 'rder il. is a channel bar 1st which has e. therein.

cate of the'one shown, there are a plurality of the channel bars 14 which are equally spaced one from the other. These saddles l5 support and carry the tank which is guyed or steadied by the guy rods 16. A. runnin board 17 is carried on each side of the tank 10 by the protruding ends of the channel bars 14 and the bolster structure (indicated generally as B). A plate 18 extends from each end of each channel bar 14 to the adjacent side of the girde'r A where it is se-y cured to the lower flange thereof. This plate acts as a support for the-extreme ends of the channel bars 14: and at the same time partially dissipates the strains and stresses set up. The plates 18 are rigdified by the diagonal struts 19 inter osed between said plates and the undersi es of the channel bars 14.

Fastened to the top flanges of channels 11, between bolster B and channel bar 14 or between adjacent bars 14 are a air of longitudinal Z-bars 20, the lower egs of which are inwardly pointed and maintained in place by rivets closely spaced. The upper legs of these Zbars are bent upwardly on an arc. of a circle so as to form a central, rigid, fastening of the tank to the girder A. These bars are first riveted to the girder A and then the tank is seated on said bars and riveted thereto. Said Z-bars 20 have their opposite ends closely abuttin the bolster B an the channel bar 14, or a jacent bars 14, as clearly seen in Fig. 1, thereby presenting resistance to end movement of said Z- bars, in addition to the rivets by which they are fastened to the girder A. It is thus observed that thc tank is rigidly fastened to the girder medially of its length by riveted members, the strength of which is suflicient to prevent any end movement of the tank on the girder. But exteriorly of this riveted section the girdcr may weave or twist considerably as the track road bed varies, without imparting undue stresses upon the tank pro er.

While herein I have disclosed the preferred method of practising my invention, I desire it umlcwftood that l may maire such chan rf" and ai nations therein as might "v themselves to the skilled mechanic emitted minier the lrmtrino oi equiv lltl nayseii' by Lettere' Patent tot the United States 1L, The combination `with. a llc'ng'ituc'iinaiA girder of a piuraiity of transverse members thereon, a 27m-plate on each side of said grder between adjacent members, the' opposite ends of said uplates abutting said members,

and a tank tired to said'Z-piates.
